不同年龄段脊髓型颈椎病动态MRI对照研究

Dynamic MRI Investigations on Myelopathic Cervical Spondylosis of Patients with Different Ages

目的分析脊髓型颈椎病患者MRI动态变化,探讨不同年龄段脊髓型颈椎病患者MRI差异。方法90例中青年脊髓型颈椎病患者及60例中老年颈椎病患者均行中立及后伸位MRI检查,观察两样本椎间盘突出、黄韧带增厚及椎管狭窄程度在中立位及后伸位的变化。结果中老年组后伸位椎管狭窄程度较中青年组加重,后伸位黄韧带增厚比例较中青年组多。结论椎间盘及黄韧带退变的发生与发展与年龄呈正比,后伸位较中立位更加明显;对于椎管狭窄程度的判断,后伸位可作为中立位的有效补充,为临床手术方式的选择提供帮助。

Objective To analyse MRI dynamic change of spondylotic myelopathy,and study the difference of spondylotic myelopathy at different ages.Methods 90 cases of young and middle-aged with spondylotic myelopathy and 60 cases of middle-aged and elderly patients with cervical spondylopathy were performed with neutral and back stretch MRI examination,to observe the changes of sample disc herniation,yellow ligament thickening and spinal canal stenosis degree in the neutral position and back stretch changes after stretching out.Results compaired with that of young and middle-aged cases,the stretched spinal canal stenosis degree of middle-aged and old cases.was aggravated.while the rate of stretched yellow ligament thickening is higher than that of young and middle-aged group more.Conclusion the occurrence and development of intervertebral disc degeneration and yellow ligament than neutral position could appear positive ration with ages.Stretch is more obvious;For judgment of spinal canal stenosis degree,the stretched could be used as the effective supplement for the neutral position.
